SELF-CLOSING FAUCET.

SPECIFICATION forming 'part of Letters Patent No. 278,597, dated May 29,1883. V i l Application filed December 9,1882. (No model.)

To all whom it may concern Be it known that W,'ANTON PRIER, CHARLESDOHERTY, and PIERCE E. EVER- ETT, citizens of the United States,residing at Kansas City, in the ,countyot' Jackson and 5 on said end ofthe valve-stem, substantially as' hereinafter more fully set forth.

In the accompanying drawing the figure is a sectional elevation of ourimproved automatically-closing faucet.

In carrying out our invention we employ the faucet spout or nozzle Alandthe upright pipe A, with whichthe spout or nozzle is cast or connected,so that the lowersurfaceof the inner end of'thespoutwill form the top ofthe 2 5 pipe, the bottom surface of the interior of the spout or nozzlebeing inclined downward from it siextreme inner end around the valveseat or opening therein toward its outerend. The purpose of thisconstruction is to prevent the water standingaronnd the valve seat oropenin g and freezing thereat in cold weather. B is the valve-stem,andB. its'valve, thelat; ter being conoidal in form, with itstaperingsurface projecting upward into and fitting 5 within the opening in thetop of the pipe A, formed, asalready stated, by the lower inner surfaceof the spout A, the sides of said opening being coincidently inclined toform a seat, as at a, for the valve, The valve 0 is fitted uponareduction of thestem, with its upper end resting against the shoulderthus formed on the stem,said valve being secured tdthe stem by a nut, b.The valve-stem B passesup through a water-tight aperture in a 5partition or seat, O,formed or cast with the inner upturned portion, Aof the spout or nLozzleA in the same vertical plane with the valve-seatbpenin g a. The seat or partition 0 l is preferably concaved, and has anair-aperture, 0, through it. i l

D is an elastic inverted cup-shaped cushion or spring, with its flaredlower surface resting on theupper outer surface of the partition or seat0, forming an air-chamber, D, between said cushion and partition, whilethrough the w upper surface of the cushion passes the upper end of thevalve-stem B, to, which it is con-' nected by a shoulder, d, on thestem, arranged to lit against the under side of, the cushion, and a pin,Yd, passed through an aperture in the'valve-stem, between the projectingends of which pin and the cushion or spring is interposed a washer ordisk, 6.

. E is an annular packing or ring, fitted within anexternally-screw'threaded ueck,f, formed upon the upturned portion A ofspout A,said packing or ring bearing upon the flared or flanged edge ofthe spring or cushion. The packing or ring E is itself secured in placeby means of the cap F,providedwith an inter- 7o nally-screw-threadedflange, which screws up-- on the externally-screw-threaded neck f of thespout A, said cap also having a shoulder, upon its inner surface,fitting upon the upper surface of the packing or ring.

Gris the valve-operating lever, pivoted to the inside of the cap F andadapted to bear or rest upon the extreme upper end of the valve-stemB,and to extend through a vertical slot, h, in the cap a suitabledistance beyond the cap to be conveniently grasped and operated. I

It will be noticed that when the lever is moved so as to cause it toforce the valve-stein, with its valve, downward, causing the valve toleave its sea-t, which will of course allow the 8 water to pass from thepipeA and be dis charged, the cushion or spring D will yieldor becompressed, and that when the lever is released the distending orexpansive action of the spring or cushion D will cause the lifting 0 ofthe valve and its stem, and thus automatically stop the flow of water,while simultaneously the suction action produced by'the in. rushing ofair through the aperture 0 into the chamber -D' beneath the cushion orspring D 5 will prevent the valve having a hammering action upon itsseat. a

Havingthust'ullydescribedourinvention,we claim and desire to secure byLetters Patent--- 1 In a. faucet, the pipe A, provided with I00 thenozzle or spoutAat its top end, said spout having its bottom surfaceinclined: outward around the communicating opening between it and thepipe, substantially as and for the purpose set forth.

2. In a faucet, the combination, with the nozzled or apertured pipe andthe valve and 1 its stem, of the partition 0, having an aperture, c, theelastic "inverted-cup-shaped cushion "or spring, and the valve-operatinglever resting upon the valve-stem, substantially as and for the purposeset forth.

3. In a faucet, the combination of the pipe A, having the spout ornozzle A, provided with the valve opening or se at,a screw-thread- 15 edneck, f, and apertured partition 0, with the valve and its stem B,having a shoulder, d, plate 0, and pin 01', the elasticinverted-cupshaped cushion or spring D, packing-ring E, screw-threadedcap 13, and the lever G, sub- 20 stantially as and for the purposespecified.
